Q. Ortner's syndrome occurs due to?
A. Single ventricle with normally related great vessels
B. Anomalous left coronary artery from pulmonary artery
C. Dilated left atrium causing compression of trachea
D. Enlarged pulmonary artery compressing recurrent laryngeal nerve
Answer: D. Enlarged pulmonary artery compressing recurrent laryngeal nerve
Explanation:
Ortner's syndrome is a rare condition and occurs because of compression of recurrent laryngeal nerve by cardiovascular structures. Most common cause is dilated left atrium due to severe MS. However, other causes include enlarged pulmonary artery, thoracic aortic aneurysms, aberrant subclavian artery which may cause compression of recurrent laryngeal nerve.
Note: Ortner's syndrome does not occur due to compression of trachea.
